Zoe's leg bones provide essential support and structure. Muscles connect to these bones via tendons, resulting in movement of the bones when muscles contract. The joints in Zoe's legs facilitate bending and flexing in particular ways.
Response:
Each year, the population increases by 40 squirrels.
Details:
The annual death rate is 0.02 per person, with a birth rate of 0.06. For a population of 1000, the annual deaths amount to 1000* 0.02 = 20. Conversely, the yearly births total 1000* 0.06 = 60. Therefore, the net addition to the squirrel population each year is 40.
In leaves, surplus glucose is swiftly transformed into starch. During photosynthesis, plants generate glucose and oxygen by reacting with water and carbon dioxide (CO2). However, throughout this process, they frequently convert a portion of glucose into starch for storage purposes. Aug 17, 2017
<span>Air masses rise and fall because warm air is less dense than cold air; consequently, warm air ascends while cold air descends. As these air masses elevate, they carry gas molecules into the atmosphere, which adversely affects the ozone layer.</span>
Answer:
a. M_D_: 9/16 Individuals with black fur
b. M__dd: 3/16 Individuals with gray fur (1/16 MMdd + 2/16 Mmdd)
c. mmD_: 3/16 Individuals with brown fur (1/16 mmDD + 2/16 mmDd)
d. mmdd: 1/16 Individuals with gray fur.
Explanation:
Provided data includes:
- The dense pigment gene, D, corresponds to melanophilin.
- The D allele is dominant over d.
- The M/m gene determines pigment production.
- M is dominant over m.
- With D present, M/m is expressed.
- With dd, M/m is not expressed.
- DDMM, DdMM, DDMm, DdMm result in black fur.
- DDmm, Ddmm lead to brown fur.
- ddMM, ddMm yield light gray fur.
